With VARIOKIT system components, cost-effective tunnel formwork carriages can be realized which are precisely adapted to meet the needs of the respective jobsite. Requirements such as drive-through openings for trucks or single-sided wall formwork are easily fulfilled. Additional components for lifting, lowering and moving are likewise available in the rentable PERI portfolio as are safe working platforms and access means. Required technical accessories, e.g. concrete pump connections, complement the VARIOKIT solutions.

At the beginning, we were rather sceptical concerning the filigree structure. Our trust has been growing by the day – now we are absolutely thrilled. The PERI formwork carriage is extremely stable and very suitable for our daily work, it fulfils all requirements of our jobsite.
Together with the PERI engineers, we designed a customized formwork carriage solution. This allowed us to concrete two sections per week – and, in spite of the ever-present passage of transit vehicles and steep longitudinal inclination, on-time completion was guaranteed. Due to the lightweight construction and hydraulic operations, the carriage could be lowered, moved forward and set up for the next cycle in less than 60 minutes.
